Jim, The only comment I woudl make on your howto is in section 6.2 "Setting up the router's LAN interface" you appear to be trying to setup an EUI-64 address that other machines on your LAN will build on their own if autoconf is enabled... However your construction of the EUI-64 is off a bit... If you have the prfeix 3ffe:b80:17e2::/48 and the MAC of your ethernet is 00:10:5A:66:DC:33 then your EUI-64 based IPv6 address would be 3ffe:b80:17e2::210:5aff:fe66:dc33 not 3ffe:b80:17e2:fffe::10:5a66:dc33... This is generated by taking the first three octet of the EUI-64 generated from the first three octests of the MAC (00:10:5A), followed by forth and fifth octets of the EUI-64 address as FFFE, followed by the last three octets of the EUI-64 filled in by the forth, fifth and sixth octets of the MAC address thus giving you 0010:5AFF:FE66:DC33 or shortened to 10:5AFF:FE66:DC33... Finally to set the "Universal/Local" (U/L) bit you set the lowest order bit in the first octet (00 is the first octet in your example) from 0 to 1 for a globally unique IPv6 interface identifer which gives you your first octet as 02 giving you 210:5AFF:FE66:DC33 for your EUI-64 interface... If you have ipv6calc installed on your computer you can verify this by the following: undrgrid@tank:~$ ipv6calc -i 3ffe:b80:17e2::210:5aff:fe66:dc33 Address type: unicast 6bone Address type has SLA: 0000 Interface identifier: 0210:5aff:fe66:dc33 Interface identifier is an EUI-64 generated from EUI-48 (MAC): 00:10:5a:66:dc:33 MAC is a global unique one undrgrid@tank:~$ ipv6calc -i 3ffe:b80:17e2:fffe::10:5a66:dc33 Address type: unicast 6bone Address type has SLA: fffe Interface identifier: 0000:0010:5a66:dc33 Interface identifier is probably manual set or based on a local EUI-64 identifier Now if you wanted to subnet this the the :: between the prefix and the EUI-64 interface identifer could be changed to whatever subnet you wanted to use... Remembering you only have 16 bits for subnetting giving you everything from :: to :FFFF: for subnets... As well if you use the "template" option of freenet6 client config (tspc.conf) it can automatically configure your router interface using <prefix>::1 and configure radvd.conf to broadcast your prefix to your LAN via router advertisements (RA) thus removing the need to configure the routers interface at all in /etc/network/interfaces or radvd... If you have any further questions regarding this feel free to contact me directly... I currently work as an IPv6 network administrator for NTT Multimedia Communication Laboratories, Inc in Palo Alto, CA and run IPv6 both at home using freenet6 and at work... Jeremy T.
